# AI Explainer Video Generator: Explain One Idea in 60 Seconds

Most explainer tools are built for a two-minute homepage video with a presenter. In a feed, people decide in the first few seconds and they're holding their phone upright. ReelsMakerAI makes the short version: a faceless, vertical explainer of 30 to 60 seconds. Type the idea, paste your script or a blog post link, and get a 9:16 video with AI voiceover, visuals and captions for YouTube Shorts, TikTok and Reels in a few minutes.

## Who makes short explainer videos

### Founders and SaaS teams

Explain one feature, one use case, or the problem your product solves.

### Marketers and agencies

Turn a blog post or a client FAQ into a weekly Short.

### Accountants, consultants and coaches

Explain the term clients keep asking you about.

### Small businesses

Show how your returns, booking or pricing works before people have to ask.

## Teaching, not selling?

Teaching full lessons to students? The [AI educational video generator](https://reelsmakerai.com/ai-educational-video-generator) is built for that.

## The 60-second explainer structure

A long explainer can wander. A short one can't. Use five beats, and keep to one idea per video.

| Beat         | Time    | Job                           | Example line                                             |
| ------------ | ------- | ----------------------------- | -------------------------------------------------------- |
| Hook         | 0–3 s   | Name the confusion            | “Your invoice says net 30\. Here's what that means.”     |
| Problem      | 3–12 s  | Why it matters to the viewer  | “Get it wrong and you wait weeks for money you're owed.” |
| How it works | 12–40 s | Three facts or steps, no more | “Net 30 means due 30 days after the invoice date.”       |
| Example      | 40–52 s | One concrete number           | “On a $5,000 invoice, 2% early is $100.”                 |
| Next step    | 52–60 s | One action                    | “Write the due date in plain words.”                     |

## One idea per video

If you need a second idea, make a second video. A series of short explainers keeps people coming back. One long explainer loses them halfway.

## Sample: “What does net 30 mean?”

Topic typed in: Explain “net 30” on an invoice for small business owners, 45 seconds. Here's the script, line by line.

| Beat         | Voiceover                                                                                                                                            |
| ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
| Hook         | “Your invoice says ‘net 30.’ Here's what that means, and how it can cost you.”                                                                       |
| Problem      | “Net 30 means the full amount is due 30 days after the invoice date. Not 30 days after your client opens it. The invoice date.”                      |
| How it works | “Sometimes you'll see ‘2/10 net 30.’ That means the client can take 2% off if they pay within 10 days. Otherwise, the full amount is due by day 30.” |
| Example      | “So on a $5,000 invoice, paying by day 10 saves your client $100.”                                                                                   |
| Next step    | “Want to get paid on time? Write the actual due date on the invoice, not just ‘net 30.’ Follow for one money term every week.”                       |

## Why this works

The hook repeats the exact phrase people search for, the middle gives one rule and one variation, there's a single number to remember, and the last line sets up a series. Realistic style and a calm voice suit a finance topic like this one.

## Three ways to start

| Start from                 | Best for                                                                       | Use             |
| -------------------------- | ------------------------------------------------------------------------------ | --------------- |
| A topic                    | Ideas you can explain from general knowledge, like terms, concepts and how-tos | The main editor |
| Your own script            | Product features, pricing, anything where details must be exact                | Script to video |
| A blog post or article URL | Repurposing posts you've already published                                     | Link to video   |

## Explaining your own product?

For product explainers, paste your own script into [script to video](https://reelsmakerai.com/script-to-video). The AI doesn't know your product, and you don't want it guessing at features or prices. To repurpose a post, paste its URL into [link to video](https://reelsmakerai.com/link-to-video).

## How to make an explainer video in ReelsMakerAI

1

### Pick one idea

Write it as a question a customer would ask: “What does the Pro plan add?” beats “Pro plan overview.”

2

### Add your input

Type the topic, paste your script, or paste a blog URL.

3

### Choose a visual style

Realistic or cinematic suits business, finance and B2B topics. Comic or anime suits lighter consumer products. There are 12 styles to pick from.

4

### Pick a voice and caption style

Choose from 120+ AI voices and keep the same one across a series so it sounds like your brand. Voiceover works in 10+ languages, so you can make the same explainer for another market.

5

### Add your branding

Your logo, fonts and colours from your brand kit go on every video.

6

### Render, check and post

Read the script against your facts, then download the MP4, auto-post it to YouTube, or send it to your TikTok drafts.

## Turn a row into a series

Run one row as a weekly series and you have a month of content from a single afternoon. Real estate agents can go further with the [AI real estate video generator](https://reelsmakerai.com/ai-real-estate-video-generator).

## What ReelsMakerAI does, and what it doesn't

We'd rather you pick the right tool.

### No presenter on screen

ReelsMakerAI explainers are faceless: voice, visuals and captions. If you need a person talking to camera, an avatar tool is the better fit.

### No screen recording

AI visuals can't show your real app. For a UI walkthrough, record your screen, or add screenshots in the editor after rendering.

### Built for short and frequent

It shines when you need one clear idea, many times a month, in vertical format. Videos run from 30 seconds to 3 minutes.

## What it costs

A one-minute Short costs about 16 credits: 10 to generate and 6 to export. Starter is $19/month (or $16/month billed yearly) for 400 credits, about 25 one-minute explainers, enough for one every weekday. Growth is $39/month for 900 credits and 2 automated series that post daily. Pro is $79/month for 1,800 credits and 3 series that post twice a day. Paid plans export in 1080p with no watermark, with a 7-day money-back guarantee if no credits are used. See [pricing](https://reelsmakerai.com/pricing).
